Section 6 ROM
Sample Program for Programming One Byte
This program uses the following registers:
R0H: Used for erase block specification.
R1H: Stores programming data.
R1L: Stores read data.
R3:
R4:
R5:
R6L: Used for the program-verify fail count.
Arbitrary data can be programmed at an arbitrary address by setting the R3 (programming address)
and R1H (programming data) values.
The values of #a and #b depend on the operating frequency. They should be set as indicated in
table 6.11.
